At 640, every major loan program is available: FHA at 3.5% down, conventional at 620+, VA if you've served, and — new at this level — USDA automated approval, which typically starts at 640 and offers zero-down loans on eligible rural and suburban-edge properties.
Conventional pricing is still mid-tier at this score, so it pays to compare an FHA quote against a conventional one. The crossover point where conventional clearly wins tends to arrive around 680–700, or sooner with a bigger down payment.
If you're buying outside a major metro, check USDA property eligibility — zero down with competitive rates is hard to beat, and this score clears the usual 640 automated-underwriting floor.
Take a buyer earning $85,000 a year, with $400/month in existing debt and $25,000 saved for a down payment, on a 30-year loan:
| Estimated rate at a 640 score | 6.95% |
| Max home price (bank approval estimate) | $252,000 |
| Estimated monthly payment (P&I + tax + insurance) | $1,980/mo |
| Same buyer with a 760+ score | $257,000 |
| Buying power cost of a 640 score | −$5,000 |
With less than 20% down on a conventional loan, PMI at this score typically runs $45–65 per month per $100,000 borrowed — meaningful, but it cancels automatically once you reach 20% equity.
At a 680 score (estimated 6.75%), the same buyer could afford about $254,000 — $2,000 more house for the same income and monthly budget. Each 20-point tier (660, 680, 700) buys a slightly better rate and cheaper PMI. Keep card utilization under 30%, avoid new credit before applying, and check all three reports for errors.
